REGENRATlVE GAS-BURNER.

g Application filed June QG, ISS-l. Serial No. 136,052. (No model.)

.To a/ZZ whom, it may concern.-

Be it known that I, Cimnnns M. Luxuria-1N, a citizen of the United States, and a resident of' New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification.

My invention relates to regenerative gasburners, and more especially to a form dcscribed in another application l'or patent heretofore led by me, and patented .I une 24, 1884, No. 300, S79, and consisting of an inverted gasburner, a flame plate or surface over which the flame is directed, andan upwardly-extending flue for the escape of the products of combastion.

My invention lconsists in certain combinations of parts and peculiarities of construction designed to produce better combustion and to give greater luminosity to the ilaine, which combinations and constructions will be herein described in connection with the accompanying drawings, and will be then specified in the claims.

In the accompanying drawings, Figure l is a vertical central section of a burner containing the improvements herein claimed. Figs. 2, 3, 4 are vertical sections ot' burners, showing modified ways of carrying out the invention. Fig. 5 is a cross-section through the gasburner tubes. Fig. 6 is a horizontal crossseetion illustrating the arrangement of the air ducts or passages conveying air to the root of' the dame.

G, Fig. l, indicates a gas-tube bywhich the burner is supported, and which conveys gas to the gas-burner. At the lower end of said tube is a gas-chamber closed at the bottom by a suitable plate, G, while from lsaid chamber extend downwardly a series of tubes, g g, (shown in cross-section, Fig. 5,) which are open at their lower ends, and are properlyarrangcd to project a llame over a vflame plate or director, D, of preferably porcelain or other refractory material.

Instead of a series of tubes, the burner may consist of' an annular chamber having openings either in the lower edge or in its outer wall near the bottom, as shown in my previous application. The plate D may be of any desired form or shape, and I do not limit myself in this respect. It may be supported by its lower edge, as shown, or by the top, and it may be a separate piece, as shown, or be formed by contracting the lower end of the air-shell A. A button or deflecting-surface, B, of any suitable kind, placed below the flame and suspended by a rod, R, serves to deflect air outwardly against the flame and the flame outward and over the plate D. Air is delivered to the root of the flame and on one or both sides thereof' through the chamber or tube in which the tubes g are contained. The passage for the egress ofthe flame and air is made sufciently contracted to cause the air-current to come into direct and full Contact with the flame at its root.

A A indicate two shells or chambers, one within the other, and connected by a series of' radiating passages, a a, as indicated in Fig. 6. The outer shell, A, is provided with a downward extension, C, for causing the flames and products of combustion to sweep inward away from the globe G, which latter is hung from and closes thc mouth ofthe tube A. The tube A supports the chimney F, through which the products ot' combustion and heated air escape after circulating around the cross-tubes a a, and heating the air conyeyed through the latter to the chamber formed by the tube A, and

through the latter io the root of' the flame.

A indicates an outer shell or hood depending from the shell A, and surrounding the outer ends of the tubes a a.

S indicates a reflector hung from A. Air is brought to the tubes a a through the hood A.

In order to do away with the tendency to redness or want of luminosity in the body and tip of the flame which may exist when the burner is constructed as thus far described, so that the passages at the root of the flame are arranged to cause the air to strike the dame fully, I provide an additional air-suppl y for the body and tip ol' the llame through the bottom or top ol" the globe by the devices to be now described.

H indicates a tube, which extends through an opening in the bottom of the globe, and is hung from the red R lby any suitable means,

cris otherwise supported. Its upper end opens roo beneath the deiccting-plate B, and between its flaring mouth and the under surface of the plate B air is delivered to the body of the iiame. The additional air thus supplied is heated in its passage to the flame through the chamber or conduit, one wall or surface ofwhich is formed by said deflecting-plate. The bottom of the tube H is partially closed by a button upon the rod It, which button may be screwed up and down to adjust the amount of the additional air-supply thus provided.

In the modification shown in Fig. 2 the additional air is supplied between the edges of an opening in the bottom of the globe and the edges of a glass`plate,K,closing said opening. The edges of the plate or of the opening, or both,are made irregular or provided with suitable crimps, corrugations, grooves, or slots,to permit air to enter in limited or regulated quantity. What heat is imparted to the additional air-supply thus provided'comes from contact with the sides of the globe.

In Figure 3 the additional air-supply is admitted at the top of the globe,and is heated by the shell C, through which latter the heated products of combustion pass. The globe is hung from a perforated ring, E', suitably attached to or supported by the shell A, and the air enters th rough said perfor-ations. The shade S is in this instance hung from the same ring, so as to assist in collecting and delivering the air through said openings, and to also prevent baclr-draft or tendency of the flames to eseape.through said openings. For this purpose the shade preferably extends below the level of -the iame. Instead of being Y a shade, the part S :might be of glass or other translucent material.

In the modification of my invention shown in Fig. 4 the additional air supplied to the body of the iiame is not only heated by the es` caping products of combustion, but also by contact with the under side of the deilecting plate or body, as in Fig. 1. In this instance the detlector B is formed at the bottom of a tube or shell, B', contained within the burner and connected at its top with the chamber formed by shell A, so that a portion of the i air entering through the tubes au, and heated by the escaping products of combustion, may pass through the tube. B and be delivered to the body and tips of the flame.l The tube or shell B is hung from the rod It, or supported in any other suitable manner in'the position shown. In the drawings it is shown as supported by anut, b, which is provided with radiating arms attached to the interior of the tube B', and is adjustable on the rod so as to vary the position of the deflecting plate or surface B, formed upon or attached to its lower end. A

If desired, the gasburner may be made with- Out any air-passage through it, and the whole of the air to supply the under surface of the ilame may be admitted through the base of the globe, or part oi' it through the base and a portion through. the top.

I do not limit myself to any particular form of gas tip or burner, nor to any particular shape or configuration of dame plate or surface over which the dames are made to sweep. The construction and arrangement may be varied in other ways without departing from the spirit of my invention, and the arrangement shown inthe various figures of drawings may be used in various combinations for the same burner.

I am aware of the English Patents No.3,742, July 3l, 1883, and No. 4,109, August 28,1882, and I make no claim to the constructions shown therein.
